Matrix as a Stack of Row Vectors
A matrix can be conceptualized as a vertical arrangement of its row vectors. If each row of a matrix is represented by a row vector , then the entire matrix can be written as a stack of these vectors from to . This is expressed as:

A computational model represents the three words in the sentence 'AI models learn' as three distinct numerical vectors:
v1 = [0.1, 0.5],v2 = [0.9, 0.2], andv3 = [0.4, 0.7]. To process these words as a single, ordered sequence, how should these vectors be organized into a single matrix?Interpreting Matrix Representations in a Language Model
